Evening wonder if anyone can help?

I have the above fault code. I have checked resistance levels for deployable on iid and my scan tool.

They are all mid 2ohm except number 7 which is 10.2ohms which i assume is open circuit as it gives the same ohm reading for no.4 if i disconnect one of the other connectors

Can anyone tell me which airbag or pretensioner is number 7 please and which pins on what connector?

Ive checked the black and grey connectors under the drivers seat, also cant see anything out of the ordinary on the harness.

Driving me insane. 2005 rrsport

Many thanks.

Anyone? 🙃

hope this helps

Thanks mate had a look at the seat position sensor in live values and it shows its in the correct position. Also shows when moved etc.
